Wolschleger Wolschlager John

This is making me nuts.I am researching John Wolschleger born 4-3-1841 in Germany, died in 1902 Huron County.Married Theresa Rose Kanthak 1852-1931.There is another John Wolschlager born about 1854 or 1858 who married a Marie/Matilda.DOES ANYONE KNOW THE RELATIONSHIP BETWEEN THESE 2 MEN?HOW ABOUT THE RELATIONSHIP BETWEEN THEM AND THE OTHER 2 FAMILIES THAT TRAVELED WITH THEM?

Also accompanying them on the voyage were the August Wollschlaeger family and the August Mausolf family, shown as: August Wollschlaeger, age 56, farmer; Elise age 52; Anna age 26; Michael age 18; August age 17; Susanne age 16; Marie, child age 7.
